ISIS has taken nearly 700 people hostage including several European and US Nationals in Syria and has vowed to kill 10 a day, Vladimir Putin has claimed.
The jihadi group is holding their prisoners captive somewhere south of the Euphrates River in the war-torn nation.

Speaking in the Black Sea resort city of Sochi, Putin added that ISIS was expanding its control in territory controlled by U.S. and U.S.-backed forces and blasted America for a “catastrophic” failure.
